Two clues at the Advent website have a series of letters that when combined produce "VIGILO CONFIDO", or the motto of Enemy Unknown 2012. It seems that a new XCOM game is under development and more details should be announced later.

May 27th, 2015

2K has released yesterday a link to a site that presents an alternate reality company called Advent Administration. Its contents have triggered speculation on the 2K official forums and Xcom subreddit that it is related to a new upcoming XCOM announcement. The site contains a rotating globe, pictures depicting a XCOM: Apocalypse style city, one of which seems to contain artwork already present on XCOM: Enemy Unknown, and a downloadable .pdf file uses a font called 'XCOM-Regular'. The site also appears to be under some sort of hacking by an unknown party, with its contents being replaced by phrases such as 'we are still watching'. While all of this is merely circumstantial evidence, 2K is expected to announce a major title on the next E3 Conference in 3 weeks so keep tuned for further details.
